Definitions

  • the present invention relates to a speed changer for a fishing spinning reel.
  • a fishing reel may have a two-stage speed changer.
  • the drawback in such a device is that a fishing reel whose handle can be attached to both of the right and left sides of the reel, has not been able to use the the conventional two-stage speed changer.
  • An object of the present invention is to provide a spinning reel speed changer for use with a reel having a handle that is attachable to either of the right and left sides of the reel.
  • Another object of the present invention is to allow for easy change of the reel rotation speed.
  • a further object of the present invention is to allow for simple assembly, disassembly, checking, and maintenance of a reel rotation speed changer.
  • a further object of the present invention is to overcome the problems and disadvantages of the conventional reel speed changer.
  • FIG. 1 shows a side view of an embodiment of a spinning reel including the speed changer of the present invention
  • FIG. 2 shows a sectional view of an embodiment of the spinning reel of FIG. 1 along a line II--II;
  • FIG. 3 shows a sectional view of an embodiment of the spinning reel of FIG. 1 along a line III--III;
  • FIG. 4 shows a sectional view of the spinning reel of FIG. 3 along a line A--A;
  • FIG. 5 shows a sectional view of an embodiment of the spinning reel of the present invention along a line V--V shown in FIG. 3;
  • FIG. 6 shows a front view of a clutch cam in an embodiment of the spinning reel of the present invention
  • FIG. 7 shows a side view of an embodiment of the spinning reel of the present invention provided with the speed changer.
  • FIG. 8 shows a cutaway rear view of an embodiment of the spinning reel of the present invention.
  • the speed changer of the present invention is provided with a hollow rotatable gear shaft rotatably supported through the body of the spinning reel such that a handle can be attached to either end of the gear shaft.
  • a master gear shaft is provided having a large speed change gear and a small speed change gear axially mounted.
  • a first speed change gear is axially mounted on the gear shaft.
  • a clutch is axially mounted on the gear shaft and is axially slidable between a first position and a second position. The clutch includes gear teeth for engaging the first speed change gear and the large speed change gear when the clutch is in the first position.
  • Clutch pin means extend radially from the clutch.
  • a clutch cam is circumferentially mounted around the clutch and includes an annular groove extending axially with respect to the gear shaft. The groove receives the clutch pin means.
  • a clutch lever is coupled to the clutch cam and is rotatable between a high speed position and a low speed position. The rotation of the clutch lever from the high speed position to the low speed position rotates the clutch cam to cause the clutch pin means to be moved along said annular groove in a first direction to slide the clutch to the first position to engage the gear teeth with the first speed change gear and the large speed change gear.
  • Rotation of the clutch lever from the low speed position to the high speed position rotates the clutch cam to cause the clutch pin means to be moved along the annular groove in a second direction, opposite to the first direction, to slide the clutch to the second position to engage the gear teeth with the second speed change gear and the small speed change gear.
  • a clutch is fitted on the hollow gear shaft so that the clutch can be rotated together with the hollow gear shaft, and can be slid, in the axial direction of the clutch, and either engaged with or disengaged from the speed change gears.
  • a clutch lever is composed of right and left portions, and a bar is attached thereto so that the clutch lever is formed symmetrically with respect to the transverse direction of the reel.
  • the clutch lever is attached to the body of the reel so that the clutch lever is turnable. Further, this attachment allows for the axis of gyration of the clutch lever to extend in the transverse direction of the body of the reel.
  • Clutch pins are slidably fitted in three types of grooves: oblique guide grooves provided in a clutch cam, capable of being turned by the clutch lever; slender grooves that slenderly extend in the axial direction of the support portion of the body of the reel; and an annular groove that is provided in the clutch along the circumference.
  • the clutch lever can be easily operated by either of a right and a left hand to shift the spinning reel clutch into either high or low speed.
  • the beneficial result achieved is that the user may quickly adjust the speed of the spinning reel depending on the size of a hooked fish, the magnitude of the pulling force of the fish, the direction of movement of the fish etc.
  • the user may employ the same hand for rotating the handle to wind a fishline to instantaneously put the spinning reel at either high or low speeds.
  • the clutch lever comprises right and left portions and the bar is attached by screws.
  • FIGS. 2, 7 and 8 two individual covers 1b are secured to the right and left sides of the casing 1a of the spinning reel body 1 by screws 2.
  • a rotor 3 is rotatably supported by a quill 4 located in front of the reel body 1.
  • a spool 6 is secured to a sliding shaft 5 slidably inserted in the quill 4.
  • a master gear 8 is rotatably supported in the right and the left covers 1b, by bearings 7 and engages a pinion 9 on the quill 4.
  • the sliding shaft 5 is movingly connected to the master gear 8 through a reciprocation mechanism 10.
  • the rotation of the master gear 8 turns the rotor 3 in a prescribed position which reciprocates the spool 6 backwardly and forwardly to wind a fishline which is located on the spool.
  • Large and small speed change gears 11 and 12, respectively, are integrally formed on the shaft 8a of the master gear 8.
  • a hollow gear shaft 13 is rotatably supported at both its ends with bushings 14.
  • the hollow gear shaft 13 extends transversely through the reel body 1 in parallel with the master gear shaft 8a. As a result, the hollow gear shaft 13 is prevented from moving in the axial direction.
  • a handle shaft 15, having a polygonal cross section, is fitted at one end with a handle 16.
  • the handle shaft 15 is inserted into the hollow gear shaft 13 and a clamp screw 17 is inserted into the other end of the hollow gear shaft and tightened.
  • the handle 16 can be attached to either of the right or left sides of the spinning reel to rotate the hollow gear shaft 13.
  • Speed change gears 18 and 19, respectively, are rotatably fitted on the hollow gear shaft 13, and engage the small and large speed change gears 12 and 11 on the master gear shaft 8a.
  • an opening 13a is provided in a circular portion of the hollow gear shaft 13.
  • the cylindrical clutch 20 is provided at one end with a plurality of projections 20a.
  • the speed change gears 18 and 19 are provided with a plurity of recesses 18a, and a plurality of recesses 19a, respectively.
  • Cylindrical support portions 21 and 22 are provided in the right and left covers 1b of the reel body 1.
  • the clutch 20 is slidably fitted in the axial direction in the cylindrical support portions 21 and 22.
  • a cylindrical clutch cam 23 is rotatably fitted on the support portion 21.
  • the circumferential wall of the clutch cam 23 is provided with guide grooves 25, which are located in mutually opposite positions, and extend obliquely along the axis of the clutch cam.
  • the circumferential wall of the support portion 21 is provided with slender grooves 24 which slenderly extend in the axial direction of the support portion 21, and are located in mutually opposite positions corresponding to those of the guide grooves 25 of the clutch cam 23.
  • the outside circumferential surface of the clutch 20 is provided with an annular groove 26 corresponding to the slender grooves 24 of the support portion 21 and the guide grooves 25 of the clutch cam 23. Both ends of clutch pins 37 are slidably fitted into the slender grooves 24, the guide grooves 25, and the annular groove 26.
  • the clutch lever 27 is provided over the reel body 1 so that the axis of gyration of the clutch lever extends in the transverse direction of the reel body 1.
  • the clutch lever 27 can be turned in directions a and a' at either the right or left sides of the reel body 1.
  • the lower parts 28a, of the right and left portions 28 of the clutch lever 27, are cylindrically shaped and rotatably fitted on the support portions 21 and 22 such that the clutch lever 27 is rotatably supported.
  • the clutch cam 23 is fitted on the support portion 21 and fitted in one of the lower parts 28a of the right and left portions 28.
  • a bar 29 is secured to the tips of the right and the left portions 29 of the clutch lever 27 by screws 30.
